What can be inferred from a graph showing nuclear radius against nucleon number?.
- A.Nuclear radius is independent of nucleon number
- B.Heavier nuclei are always larger than lighter nuclei
- C.There is a correlation between the number of nucleons and nuclear size
- D.Nuclear radius decreases with increasing atomic number
Model answer
What a good answer should say
- There is a correlation between the number of nucleons and nuclear size
Explanation
Why this works
The evidence from the graph shows that as the number of nucleons increases, the nuclear radius also tends to increase. This correlation implies that the size of the nucleus is directly related to its nucleon count.
Thus, the conclusion is that understanding this relationship is crucial for studying nuclear properties.
